Hi,

I try to exchange datas between host and Guest by adding these lines in a guest .xml conf file :

<channel type='pty'>

<target type='virtio' name='arbitrary.virtio.serial.port.name'/>

<address type='virtio-serial' controller='0' bus='0' port='1'/>

</channel>

Then /dev/virtio-ports/arbitrary.virtio.serial.port.name is exposed in the guest and a /dev/pts/x is seen as source path on the host.

I checked that on two Linux hosts :

libvirt-daemon-driver-qemu-1.2.8-16.el7_1.3.x86_64

qemu-kvm-1.5.3-86.el7_1.5.x86_64

qemu-kvm-common-1.5.3-86.el7_1.5.x86_64

qemu-guest-agent-2.1.0-4.el7.x86_64

ipxe-roms-qemu-20130517-6.gitc4bce43.el7.noarch

qemu-img-1.5.3-86.el7_1.5.x86_64

Linux sparring 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

qemu-img-0.12.1.2-2.415.el6.x86_64

qemu-kvm-0.12.1.2-2.415.el6.x86_64

gpxe-roms-qemu-0.9.7-6.10.el6.noarch

Linux orion 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

The device is only exposed on the guest of the first host .

Is it due to a too old version of qemu and/or Linux on the second host or some packages missing on this second host ?

Thx.
